ABSTRACT

Since the Korean open data portal service was launched in 2013, the level of data openness has expanded qualitatively and quantitatively, and numerous applications using open data portal have been developed. Since 70-80% of administrative data is location-related information, most of portal data also have spatial information. This study proposes spatial data improvement schemes of open data portal. To do this, at first, the 3 data types(file data, open API data, standard data) provided by open data portal was analyzed, and then status and problems of spatial data in portal were analyzed. Through status analysis, this paper suggests some improvements schemes. At first, a system for determining the data type, information level, and format of data should be established. Secondly, it is necessary to diversify data management institution and examine relevance of the data format. At last, in terms of the use of spatial information, the exact information of reference system should be provided and an integrated API for transforming the location reference system should be developed, and the handling process of irregular location reference system should be examined.
